This is intended to be just stating a fact.
Would you mind elaborating on your comment?

Coming back to this document, the attribute is related to node indicated in the BGP NEXT_HOP which is usually not far away from you, including from a trust perspective. Also this attribute is explicitly removed when the NEXT_HOP is changed, and the attribute is non-transitive.
Finally, the first application is for labelled (MPLS) routes which typically imply a trust boundary.

Thanks,
Regards,
